After a measurement

Is there a way with Javascript to invoke  this.exportAsXFDF({cPath:(\C\Test\Test.XFDF), bAnnotations:true});  just after a measurement is finished? So the info is added to the file at that moment. For document-level script (would rather have it as file-level script but that is not possible).

if (condition) {
 

     this.exportAsXFDF({cPath:(\C\Test\Test.XFDF), bAnnotations:true});

     }
